Alienware 15R3 BIOS issue

Today I received my Alienware 15R3 7700hq laptop. I installed a m2 ssd and two sticks of 8gb ram. Everything was working fine.  I went onto the dell website and downloaded all the necessary drivers/windows updated as well. Lastly I decided to flash the bios with the latest version as it was recommending me too. 

Now if I had known that there is a problem with flashing the bios and it seems to be bricking many Alienware 15R3 laptops I wouldn't have done it. The bios seemed to flash ok though when it went to restart it just hung with a black screen and fans on full power. Only the left side of the keyboard was lit up middle and right wasn't. 

Having done on a quick google I realised there was definitely an issue. I decided to follow the procedure of doing a hard reset and hoping the laptop would turn on with no issues. 

There was a big issue unfortunately, black screen followed by 7 beeps. Fans and lights all light up just nothing on the screen. 

Now I understand that my laptop has broken and the BIOS has bricked it however I can't seem to do anything to get anything up on the screen. I've unplugged the battery, drained the power, done a cmos reset, taken ram sticks out (doing this and powering up doesn't even give any beeps, RAM is fine though, which I find strange). I have also tried holding fn and powering up to no avail. The strange thing is though once I had done these procedures the laptop starts and resets 3 times (clicking?) then it's followed by the 7 beeps. If I power off and power on again no beeps but no display either. It will just hang until I force shut it off holding the power button. 

I don't believe my cpu or motherboard has died as usb/mouse etc all light up fine. I believe the latest bios is the cause of this and I cannot understand as to why this has happened as my laptop was plugged in using the power supply provided. I also didn't interrupt the installation at any point

Now, where do do I stand with this? As it's from the dell uk outlet. Can anyone help? Also has a years warranty?
